BINDER.

Patented Sept. 15, 1914.

Be it known that I, JAMES R. MOFFATT, a citizen of the United States, residing at Chicago, in the county -of Cook, State of Illinois, have invented certain new and usefollowing is a description, reference being had to the accompanying drawing, and tof the letters and figures or reference marked I thereon.

My invention relatesto an improvement in devices for folding and guiding aband or strip to the stitch-forming mechanism of a sewing machine to be folded around the edge of a'fabric, and stitched thereto as a binding strip.

The invention includes several novel features, all as hereinafter described and referred to in the appended claims.

The invention is illustrated in the accompanying drawings in which,

Figure l is a front elevation of a sewing machine, showing my invention applied thereto; Fig. la is a plan view of the same, partly in section; Fig. 2 is afront elevation of the folder and guide for the band before it reaches the binder; Fig. 8 is a plan view of the same; Figs. 4 and 5 are detail views illustrating the two overlapping plates; Fig. 6 is a plan view of the binder; Fig. 7 is a similar view of the same, the parts being in a different adjustment; Fig. 8 is a top plan view of the cloth plate slide of the machine; Fig. 9 is a top plan of the binder detached; Fig. l() is a side view of the same; Fig. l1 is a plan view of one of the adjusting plates,

detached; Fig. 12 is a bottom view of the other adjusting plate, detached; Fig. -13 is a sectional view showingA the adjustable stop for positioning the binder; Fig. 14 is a front S--i enlarged view, showing thefabric as it passes from the binder, and Fig. 15 is a section through the support for the edge guides coperating with the binder.

The machine is of any well known construction, but herein is shown as of the Union Special single needle type. Upon the cloth plate is adjustably secured a plate A, carrying the preliminary folder and guide for the binding strip, which folder and guide is constructed as follows: Attached to the vertical flange a, by the screws b, I2', is the tapering folding guide B. J

C, C', are overlapping guiding plates for the band, both having their Shanks pivoted on the screw b and adjustable to vary the ful Improvements in Binders, of which the size of the guiding opening formed by the overlapping ofthe plates by means of the elongated slots d. The plate C `has the flattened wire loop c, through which the band passes, the adjustability of the plates C, C', allowing for the guiding of varying widths of bands into the folding guide B.

D represents the binder proper, attached to the cloth plate slide E, by screws e, e. This binder instead of being solid at its front edge, as is customary, thus requiring the threading of the strip from the end, is self-threading, that is, has a slot f, with aring walls, through which the upper and lower sides of the binding are' inserted, above and below the solid central portion g, of the binder, the walls of the blnder above and below the solid central portion being of spring material.

The binder is set to proper position to regulate the bite of the needle into the binding by means of a gage plate F. The binder as above noted is mounted upon and carried by the cloth plate slide E and it will therefore be obvious that if the slide plate E should be moved toward or from the needle that the position of the binding strip being stitched will also be altered and the bite of the needle into the binding strip determined. The gage plate F is adjustably attached to the sliding plate E by slot and screw connection IL, z. This gage plate F has its forward end slightly bent downward so that when the cloth plate slide is moved. toward the needle the end of the gage plate F will come in Contact with the throat plate T of the machine and thusjpievent the cloth plate slide from being moved further in a direction toward the needle. It will thus be seen' that this gage plate F serves as a stop to limit the inward movement of the cloth plateslide and that said gage plate therefore serves as a means to position the binder relative to the needle and to regulate the: A-

bite of the needle into the binding.

then brought quickly back to the same operative position relative to the needles as the stop limits the inward movement of the slide. Then again, by mounting my binder on the movable cloth plate, said binder may be readil moved away fromthe right hand side of the needle with the cloth plate, and thus afford easy access to the looper for threadin the same. y

To adjust the binder to receive different widths of binding strips, I have provided the block Gr, having an inclined groove 7c to t the leather l, on the clot-h plate slide and adjustable by means of the slot and screw connection m, n. Secured to this block by a screw 0 and having limited lateral adjustment by pins and slots, p, g, is a plate H. The slot m is, of course, wider than the shank of the screw n, to allow this adjustment of the plate H. The block G and plate H, have flat fingers I, adapted to lit respectively the recesses between the central p portion g, of the binder and the lower and upper walls,so that by sliding the block G on its feather, these fingers are moved laterally to narrow or widen the binder recess, and thus to allow for narrower or wider binding strips. These fingers are cutaway as at K, to conform to the sha e of the binder adjacent the needle. This adjustment permits'the proper folding and guiding of various widths of binding strips, and

the lateral adjustment of the upper plate H,

permits an adjust-ment of the upper and lower faces of the binder with respect to each other, whereby the upper face Vof the bound fabric may be covered to a greater or less extent than the lower face, and vice versa. A

The feather on the cloth plate side, is arranged obliquely and parallel with the. oblique face of the binder, and the forward reduced ends L of the finger I are also formed on the same angle, so that when the block G and plate H are bodily adjusted, the ends of the fingers I will move in a direction substantially parallel with the oblique delivery end of the binder. It is very essential that the lingers I should never project beyond the mouth of the binder as-the fabric when leaving the binder is inverted so as to pass in a direction substantially at right angles to the direction which the binding strip or fabric passes through the binder and the edge of the bindingstrip will run over the end of the fingers I in making the turn.

Having thus -described my invention, what I claim as new and desire to secure by Letters Patent, is
